This invention relates to window installa-' tion and has special' reference, to improvements in such as pertains to the common double sash windows as used in building con-.

struction. y v

The principal object is to, provide a more conveniently assembled novel structure than illustrated in my copending applications Serial Numbers 244,162 and 322,865.

Other objects and advantages of the novel assembly will appear in the further description ofthe invention, thepreferredform of which is illustrated in the accompanying drawings, forming part ofthis application, and wherein v V Figure 1 represents a fragmental vertical section through one of the improved window assemblies;

Figure 2 is a horizontal sectional view; v Figure 3 is a somewhat enlarged vertical section similar to Figure 1 but only of the lower part and sill of thewindow showing an elevation'of the novel form of weight well entrance; e

Figure 4 isan enlarged perspective view of the closure for the weight well entrance ;and

H oFie'rc clined portion of the stop '14 for cooperative similar inclined auxiliary stop in my former application, but such stops in this applicaj tion are novel in thatthey are scarfed, the one 14 as at 18 into the head jam 3, and the one '15 as at 19 into the upper face of the. sill 4';

"and either or'both may befastened as screws or the likeas desired. Now, while I have shown'in my former application vinterlocking engagement of \the I meeting rails of the twoywindows, such interlocking arrangement has the property of drawing the rails of the, window together i when finally closed, In the present structure it is obvious that'such means is provided by the engagement of the inclined tongued auxiliary rails 20 and 21, theformer fiX6d as by I J screws or the like to theupper rail of the lower sash and the lattersimilarly attached to the lower-rail of the upper sash. These auxiliary rails are further novel in that they arescarfed or tongued and grooved into-their I respective supports, insuring atight draftproof connection. It is obvious that these auxiliaryrails are of a thickness less than the minimum distance betweenthe rails of thewindowso as to insure tightly holding the Windows, when closed, against the parting strip 5. Furthermorethese auxiliary stripsbeingreadily removable result .in a

,marked convenience in the construction-and assembly of such a window as against any at tempt at forming the strips as integral parts of their respectiveholding membersfi- Another novel featureof my present window assembly is that of the tongued and lgrooved connection of the auxiliary window sill 6 to'the window sill proper, theupper face of the auxiliary sill being stepped beheath that of the sill proper and provided 'withsa groove 22 in'the-lower face thereof for tongue and groove connectionwith the siding or sheathing of the building; and furthermore making it possible to assemble any number of windows in close juxtaposition with asingle auxiliary sill.

A further novel feature of my present assembly is that the entrance to the weight 5 wells are accomplished through a stop and side wall of the window frame; the closure comprising asingle unit as shown in Figure 4, embodying a portion 23 of the cut stop and the wedge shaped portion 2a of the side memher of the window frame, or bottom of the sashway, and which I propose to hold in po* sition by means of suitable screws 25 through the stop portion thereof.

A still further novel feature of my invention is that clearly illustrated in Figures 2 and 5 of the drawings wherein the cheek rails 26 are made in two cooperative parts, including that portion 26 and that other cooperative portion 27 they being held together when in normal operative position by suitable screws one adjacentthe uppermost end of each rail as at 2-8 and one adjacent the lowermost end. as at 29. Just conveniently above the latter are placed removable pins which afford pivotal connection of the parts of the rail when the screws 28 and 29 are removed. so that the windows may be tipped upon such pivotal connection downwardly and inwardly as shown in Fig- 39 ure 5 for convenience in cleaning bothsides thereof from the interior of the building. In order to provide a weather tight union between the parts 26 and 27' of the rails I have shown them united by means of a U5 rather distorted, shallow and widened'tongue and groove joint, it being shallow for the purpose of readily permitting of the yield ing of the parts when the windows are lowered, and insuring a perfect alignment when assembled in normal position by theattacliing means previously described.

From the foregoing it is evident that I have devised a novel form of window assembly, the advantage of separable parts, convenience in setting up as well as caring for same, and the possibility of readily producing a mullion window from the use of a plurality of single window frames and the auxiliary sill, being readily apparent to those versed in the art.

Having thus described. my invention, what I claim and desire to secure by Letters'Patent, is:

A double sash window assembly of the type described having means cooperatively engageable with the sashes for causing them to uniformly impinge the partin strip of the window, said means characterized by being scarfed into the supports therefor, and remova-bly attached to said supports.

In testimony whereof I aflix my signature.
